of Essex and State of New Jersey, have n vented certain new and useful Improvements in Float Devices; and I do hereby declarethe following to be a full,'clear, and exact description or theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference-marked thereon, which form a part of this'sp ecifica tion. v

This invention relates to improvements in floats adapted to be used for variouspurposes, as for example, in connec ion with any character of mechanism arranged to be actuated by the rise and fall of a float when subjected to the buoyancy of a liquid.

The inventionhas for its principal object .to provide a novel construction of float device which is not subject to loss of buoyancy by reason of leaks or the penetration thereinto'of the liquid by whichlit is sustained,

and which is provided with an impervious covering or coating so'that its internal structure or core is protected fromcontact wlth the liquid by which it is sustained, and thus maintained free from impairment, rotting or other deleterious or destructive efiects tending to defeat its operative or normal buoyancy.

Other objects of. this invention, not atthis time more particularly enumerated willbe clearly understood from the following detailed description of the same.

With the various objects of the invention .in view, the same consists, prin'iarily, in the novel structure of float device hereinafter set forth; and the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction thereof, all of which will be hereinafter more fully 7 described, and then finally embodied in the ap'pended claim.

V The invention is clearly illustrated inthe accompanying drawings, in which Figure 1 is a side elevation of the novel 2 Hunt:

' k Similar characters of :reference are employed'in all of the hereinabove described views, to indicate correspondingparts.

Be fe rring now to said drawings,the reference character 1. indicates the complete novel float device, inade according to and embodying the principles of this invention, the same comprising'a central core 2 of de The said core '2 may be made of any desirable and suitable material, but is preferably made of some material of less specific gravity than the liquid with which it is tobe employed, As examples ofmaterials which may be very satisfactorily employed for said core may be named wood, corl -pith and similar sub- Usually floats of the character involved in this invention areadapted to be connected with the mechanism they are desired to act-u- EigUre'Z; and Figure 5 is'a transverse sec-j ate by means of a connecting rod or stem. j

It is, therefore, apart of this invention to provide in comb natlon wlth the novel float structure a means for receivlng the attac ment of such a rod orstem to the core 2 of v i the float device. To this'endI provide in a suitable location, preferably so as to enter' ,nular shoulder 6, the latter being preferably countersunk in the surface or end of the core 2. Said bushing or ferrule 5 possesses an outwardly extendlng orf projecting neckportion 7 forward of said shoulder 6. Said V bushing or ferrule 5 is furtherprovided with an internally threaded longitudinally or axially disposed receiving socket 8,

which penetrates the body thereof from the outer end, and which is adapted to receive the end of a rod or stem 9to be attached to the float-, said rod or stem 9 being threaded into said receiving socket;

The reference character 10 indicates an enveloping covering or coating of moistureproof material which is applied upon the core itself is subjected to efiects, such rotting, etc. Preferably the I terial.

exterior surface of said core 2 so as to entirely cover the same. This covering or coating 10 must .be of such character that it is impervious to the liquid by which the float is to be sustained. ing provides anintegral one-piece protective means which prevents the core from becoming saturated with liquid, whereby either the bouyancy of the same is reduced, or the deteriorating material employed for saidcoating orrcovering 10 isot a plastic nature, light in weight,

and adapted, when dry or in hardened state, to provide a durable liquid resistant ma- I hav and articu :arly tor floats employed with water, that ,the 'RlGSl) satisfactory material tor-said covering or coating-1O is celluloid and similar substances, which may be *a plied to the surface of the core 2 by any 7 J.

The said covering'or coating 10 adheres firmly to the surface or the core '2, and also bonds to or forms an impervious juncture with the outwardly projectingneck-portion 7 of the bushing or ferrule 5, whereby access of liquid to or :into the body of the core is entirely shutoff at all :points.
